planters such as set forth in United States Letters Patent No. 843,500issued to J. I. Case Plow Works, assignee, February 5, 1.907 and uponwhich the present invention is an improvement.

The object of the present invention is to strengthen, simplify andimprove the construction set forth in the prior patent referred to andthe invention consists in the features of improvement hereinafter setforth, illustrated in the accompanying drawings and more particularlypointed out in the appended claims.

' In the drawings, Figure 1 is a view in side elevation of the improvedplanter. Fig. 2 is a partial view in longitudinal section thereof. Fig.3 is a plan view with the seed hopper, operators seat and bearing wheelsomitted. Fig. 4 is a rear view of the wheel axle with parts shown insection. Fig.5 is a detail section on the line 5-5 of Fig. 3.

- Fig. 6 is a detail view of a part of the shifter mechanism. Fig. 7 isa section on the line 7-7 of Fig. 6. Fig. 7 is a detail view of partsshown in Figs. 6 and 7. Fig. 8 is a detail view of the drive mechanismfor the seed-plates with parts shown in section. Figs. 9 and 10 aredetail views of the guidebox for the standard of the furrow-opener withparts shown in section.

The supporting wheels 1 for the machine are connected to the drive axle2, so that the latter rotates with the wheels. The frame of the machinecomprises inner and outer side-bars formed of wrought iron or steel andarranged on edge as shown below the axle 2. The inner side-bars 3 arepreferably constructed of a single piece shaped to form a loop, asshown, so that the rear end of the loop forms a cross-bar 4 between therear ends of the inner side-bars 3. The side-bars 3 are parallelthroughout the greater portion of their length and at their forward endsconverge inwardly and terminate in parallel portions 3 which arearranged, on opposite sides of the draft tongue 5 and are securedthereto by bolts 6. Bearing-boxes 7 within which the wheel axle 2is'journaled, are provided at their ends with downwardlyextending lugs 8provided with notches or seats 9 for engaging the inner and outerside-bars 3 and 10 to which the lugs are connected by bolts 11. Thebearing-boxes 7 are connected to the rear ends of the outer sidebars 10and the latter extend forwardly therefrom in parallel relation with theinner side-bars 3. The forward ends of the outer side-bars convergeinwardly and are provided with parallel portions 10 which over lapthe'parallel portions 3 of the inner side'- bars and are secured theretoby a pair of bolts 12. The rearmost bolt 6 also extends through theforward ends of the outer side-.

bar portions 10, so that the latter are connected to the rear end of thedraft tongue 5. The converging portions of the outer sidebars 10 areprovided with short parts 10 which are arranged adjacent and parallel tothe front ends of the parallel side-bars 3 and are spaced aparttherefrom to receive the forward ends of the drag-bars 13 that arepivotally connected to the inner and outer side-bars by bolts 14. Thesedrag-bars carry the covering shovels 15 upon vertical standards 16. Aseat-post 17 is secured to the rear cross-bar 4 by a bolt 18 and carriesan operators seat 19. The drag-bars 13 are connected by a cross-bar 20having extended pieces 21 which form foot-rests. The frame is heldagainst longitudinal movement on the wheel-axle by a pin 22 that extendsthrough the wheel-axle and is arranged to engage the outer end of one ofthe bearing boxes 7 and a clutch sleeve 23 which is mounted on the shaftand aflixed thereto by a pin 24: and arranged to engage the inner end ofthe bearing-box 7 (see Fig. 4).

At the forward part of the machine and in front of the seed mechanism,is arranged a suitable furrow-opening device, which is preferably in theform of a double mold board or middle-burster plow 25 and which formsthe trench or furrow in which the seed is planted. The furrow-openerorplow is secured to the lower end-of a vertical stand ard 26 whichextends upwardly'betwee'n the front parallel end portions 3 and 10 ofthe inner and outer side-bars 3 and 10. A guide-box is formed to receivethe standard 26 formed, as shown in detail in Figs. 9 and 10, by a. pairof wrought metal plates 27 which are arranged between the front parallelportions 3 and 10 and are secured thereto by the bolts 12. Thin bars 28are interposed between the end portions 3 and 10 of the side-bars, andthe plates 27 are spaced apart but snugly secured in position againstthe end portions 3 by spacing sleeves 29 on the bolts 12. The plates 27extend upwardly some distance above the side-bars and downwardly justbelow the same. These upper and lower extending portions are bentinwardly toward each other and the plates are c0nnect ed at theircorners by a set of tie bolts 30 having spacing sleeves 31 thereon. Thespacing sleeves 31 at the upper, front corner of the guide-box and atthe lower rear corner thereof are provided with guide-rollers 32 thatengage respectively with the front and rear edges of the standard 26.Pressure upon the plow 25 at the lower end of the standard, forces thelower portion of the standard rearwardly against the lower guide-rollerand its upper portion forwardly against the upper, front guide-roller,so that the standard is rigidly and securely held against movement inhorizontal direction but, at the same time, can be readily shifted bythe operator in vertical direction when desired. The guide-box is bracedby two sets of brace-bars 33 and 34 extending upwardly from the frame tothe upper por tion thereof. The front inclined bracebars 33 overlap thefront upper corners of the plate 27 and engage the ends of the upper,front bolt 30. The brace-bars are forwardly and downwardly inclined fromthe upper front corner of the guide-box and their front ends overlap thefront parallel portion 3 of the side-bars and are secured thereto and tothe tongue by the center bolt 6. The brace-bars 34 overlap the upper,rear corner of the guide-box and engage the ends of the upper rear bolt30 and are rearwardly and downwardly inclined and overlap the innerfaces of the side-bars 3 and are secured thereto by bolts 35, as shownin Fig. 5. The construction forms a very rigid guide-box for thevertical plow standard 26 which is subjected to great strain during theoperation of the machine. The front end of the narrow bars 28 terminatein depending lugs 36 (see Figs. 1 and 2) and a cross-bolt 37 extendsthrough these lugs. The overlapped, rear end of a strap 38 engages thebolt 37 which extends from side to side just below the lower face of thedrafttongue 5. This strap engages the lower face of the draft tongue,and a vertical bolt 39 extends through the tongue and through the rear,overlapped portion of the strap 38 in front of the bolt 37. The forwardend of the strap 38 is connected to the tongue by a pair of verticalbolts 40. The lower ends of these bolts also engage a clevis strap 41,so arranged that the lower extended end of the front bolt 40 serves as ahitch for the equaliZer or draft-bar of the team. By means of theimproved construction set forth, the plates 27 which carry the guiderollers 32 for the standard 26, is securely connected to the frame andto the draft tongue.

The seed-box or hopper 42 is provided with a suitable bottom 43 withinwhich is mounted a horizontal beveled gear 45 which drives a seed-plate44 of any suitable construction. Interchangeable seed mechanism forplanting seeds of different kinds may be arranged in a well-known mannerwithin the seed-box bottom. The seed-box bottom 43 is fixed at its sidesto a pair of brackets 46 that are secured to the rear ends of a pair ofbars 47 by bolts 48. The forward ends of these bars converge inwardlyand pivotally engage the ends of the upper, rear bolt 30 of the standardguide-box.

The brackets 46 are provided with depending lugs within which isjournaled a countershaft 49. A gear, pinned to one end of this shaft, isprovided with a beveled tooth portion 50 that meshes with the beveledgear 45 of the seed-box and with a spur-tooth portion, 51 which mesheswith the teeth of a gear 52 on the drive-axle 2. A pair of dependinglugs 53, preferably formed of wrought metal plates, are secured to thebrackets 46 and to the ends of the bars 47 by the bolt 48 and extenddownwardly therefrom below the brackets. These depending lugs or plates53 rest upon a pair of bearing sleeves or brackets 54 that are securedto the inner side-bars 3. The depending lugs or plates 53 also snuglyfit between a pair of upstanding lugs 55 on the brackets 54 to therebyhold the seed-box in position. During the operation of the machine, thegear 51 always remains in mesh with the gear 52 upon the wheel axle, butif desired, the seed-box and the bars 47 may be swung upwardly about thebolt 30 to which the bars 47 are pivoted, and the seed box may be thusshifted into a position in which the seed-plates can be readily changed.A sleeve 56 is loosely mounted on the counter-shaft 49 and aseed-delivery chute 57 (see Fig. 2) is connected to a depending lug 58on the sleeve in position to receive the seed discharged from the hopper42 by the operation of the seed-plate.

A rock-shaft 59 is journaled in the hearing sleeves or brackets 54,which, as stated,

are fixed to the inner side-bars 3. One end of the shaft is extended andis journaled in a bracket 60 fixed to one of the outer sidebars 10. Thisbracket is provided with a toothed segment 61, and a shift-lever 62fixed to the end of the shaft is provided with a locking dog 63 arrangedto engage the teeth of the segment 61 and hold the shift-lever androck-shaft in any desired position. The lever 62 is provided on its endwith a pivoted trip 64 connected as usual to the dog 63 by ,a rod 65.

connected by a double liiik 67 to the upper end of the plow standard 26by a bolt 68. The standard is preferably formed of two pieces connectedtogether as shown, and the double link 67 extends between the two partsof the standard. The upper end of the standard is provided with a seriesof holes 69 to receive the bolt 68, so that the connection between thestandard and the link 67 can be adjusted. The rock-arm 66 and link 67serve to raise and lower the plow standard and furrow-opening plow whenthe lever 62 is shifted by the operator. The adjust ment between thelink 67 and the standard permits the adjustment of the furrowopeningplow in any desired relation to .the shift mechanism which raises andlowers it from and to working position.

The lower end of the delivery chute 57 is provided with a telescopicsection 70 which is adjustably connected by a bar 71 to a rearwardlyprojecting part 72 on the lower end of the plow standard. The bar 71carries a small supplemental furrow-opener 7 3 immediately in front ofthe lower end of the seed delivery chute. This supplementalfurrowopener'and the telescopic portion of the seed delivery chute areshifted to and from working position with the plow standard 26.

The shifter rock-shaft 59 is provided adjacent its ends with a pair ofarms 74 connected thereto by bolts 75. The ends of these arms areconnected by links 76 to the ends of a pair of arms 77 that pivotallyengage the bolts 14 which serves to connect the dragbars 13 to theframe. The arms 77 are hookshaped and have inwardly projecting por-.

tions 78 at their lower ends which extend beneath the drag-bars 13 tothereby raise and lower the drag-bars as the shaft 59 is shifted oroscillated by the lever 62. This one-way connection between the arms 77and the drag-bars permit the up and down movement of the drag-barsindependent of the shift mechanism but, when the latter is operated, thedrag-bars and the covering devices carried thereby are raised andlowered.

To adjust the position of the drag-bars relatively to the shiftmechanism, or to vary the point at which they are raised by theoperation of the shift mechanism, the links 76 are adjustably connectedto the arms 74. For this purpose, the arms 74 are provided withtransverse slots 79 through which bolts 80 extend and the links 76 arearranged to pivotally engage washers 81 mounted on the bolts 80. Thewashers 80 have conical inner portions which fit within elongated seats82 formed in the arms 74 about the slots 79. The washers and the seats82 are provided with teeth 88, so that the washers and the ends of thelinks 76 are securely held in adjusted position. Byloosening the nuts onthe bolts 80, the washers and the ends of the links 76 can be adjustedback and forth upon the ends of the arms 74 to thereby vary the point atwhich the drag-bars are lifted during the operation of the shiftmechanism.

The drive gear 52 on the wheel axle is loosely mounted thereon, and. thecentral.

part of the gear is provided with a depressed portion having a series ofteeth arranged to engage the teeth of the clutch-sleeve 23 that is fixedto the wheel-axle. A spring 84 coiled about the wheel axle, extendsbetween the hub of the gear 52 and one of the bearing sleeves and servesto hold the gear normally in engagement with the clutch sleeve 28. Theother bearing sleeve 7 adjacent the gear 52, is provided with a pair offorwardly projecting lugs 85 between which a shifterarm 86 is pivotedupon a bolt 87. The rear end of the shifterarm is forked to form a pairof curved cam arms 88 which extend on opposite-sides of the clutchsleeve 23 and engage the recessed face of the gear 52. The forward endof the shifter-arm is arranged to be engaged by a cam 89 on the shifterrock-shaft 59 so as to be operated thereby when the shift mechanismraises the furrowopener and covering shovels and so shift the gear 52against the tension of the spring 84 out of engagement with the clutchsleeve 23. hen the shift mechanism is again operated to lower thefurrow-opener and covering devices to working position, the spring 84will restore the gear 52 into engagement with the clutch sleeve. Thisshift of the gear 52 into and out of engagement with the clutch sleeve23 is insuflicient to disengage it from the spur-toothed portion 51 ofthe gear on the counter-shaft 49.

To vary the point at which the shifter arm 86 is moved to throw the seedmechanism into and out of operation, the'cam 89 is adjustably mountedupon the rock-shaft 59. For this purpose, it is adjustably mounted uponthe edge. of a segment 90 which is formed in piece with one of the arms74 on the rock-shaft 59. This segment is provided wit-h a projectingportion 91 which fits within a seat on the cam 89 and the latter isadjustably connected to the segment by a bolt 92 which extends through aslot 93 in the segment.

The cam 89 and segment; 90 have interlockare all independentlyadjustable. This is desirable in machines of this type which are oftenused to break out the old furrows and at the same time plant the seed,and the seed may be planted in furrows formed by breaking out the oldhills or in the trenches between the hills, so that the working depth ofthe furrow-opening plow and of the coverers vary greatly under thedifferent conditions in which the machine is operated. But by means ofthe adjustable connections between the shift mechanism and the differentparts, the shift-lever can be maintained within easy reach of theoperator and the furrow-opening plow and covering shovels can be set towork at any desired depth while the point at which the seed mechanism isthrown into and out of operation can be adjusted to suit these differentconditions.

A bracket 95 is secured to the rear bar 4 of the frame, and carries apivoted, springheld latch 95 which is arranged to engage the cross-bar20 and hold the drag-bars 13 'and covering devices carried thereby inworking position. A link 96 connects this latch to a link 97 which inturn is connected to an arm 98 fixed to the shifter rock-shaft 59, sothat the latch is withdrawn from its position above the bar 20 when theshift mechanism is operated to thereby permit the hooked arms 77 toraise the drag-bars 13 and covering devices carried thereby. The link 97is formed of two adjustable sections, one screw-threaded in the other,so that the time at which the latch 95 is re leased can be adjustedrelatively to the throw of the shift mechanism. If desired, the latch 95can be held out of operation by a catch 99 on the bracket 94. A bar 100is held in place between the bracket 95 and the rear bar 4 and hasdepending end portions 101 arranged adjacent the drag-bars 18 to holdthe drag-bars and covering devices carried thereby against lateralmovement when the latter are in their lower, working position.

It is obvious that changes can be made in the details of constructionwithout departure from the essentials of the invention as defined in theclaims.
